inline

Construct a system solver.

Parameters

[in]	simulator	The opm-models simulator object
[in]	parameters	Explicit parameters for solver setup, do not read them from command line parameters.
[in]	forceSerial	If true, will set up a serial linear solver only, local to the current rank, instead of creating a parallel (MPI distributed) linear solver.
